There are quite a few little things you can do to better your memory and remember more of what you read. The truth is, if you don’t use or review the information you learnt within 24 hours, you will forget a great deal of it.
The good news is that once you review your certification material, your memory will bounce back to its initial learning. We will forget it again, but the second time you will forget more slowly than the first time.
As passive learners, we remember only 10% of what we read, 20% of what we hear, and 30% of what we see.
